Francis Visoiu Mistrih 25528d6de7 [CodeGen] Unify MBB reference format in both MIR and debug output
As part of the unification of the debug format and the MIR format, print
MBB references as '%bb.5'.

The MIR printer prints the IR name of a MBB only for block definitions.

Evandro Menezes 9dcf099944 [AArch64] Fix the number of iterations for the Newton series
The number of iterations was incorrectly determined for DP FP vector types
and the tests were insufficient to flag this issue.

Silviu Baranga dc43d61a25 [AArch64] Switch regression tests to test features not CPUs
Summary:
We have switched to using features for all heuristics, but
the tests for these are still using -mcpu, which means we
are not directly testing the features.

This converts at least some of the existing regression tests
to use the new features.

This still leaves the following features untested:

merge-narrow-ld
predictable-select-expensive
alternate-sextload-cvt-f32-pattern
disable-latency-sched-heuristic
